【摘要】
目的
回顾性分析厄洛替尼加减脑部放疗治疗非小细胞肺癌脑转移患者的疗效和不
良反应。方法56例经病理学证实的非小细胞肺癌伴脑转移患者采用厄洛替尼治疗,其中联合脑部 放疗者42例。观察其客观缓解率和疾病控制率。Kaplan-Meier法计算无进展生存率和总生存率并 Logrank检验,Cox回归模型进行多因素分析。结果56例患者脑病灶局部总体客观缓解率(ORR) 57.1%(32/56),疾病控制率(DCR)82.1%(46/56),中位无疾病进展时间12.3个月,中位生存时间 8.0个月。1年、2年无进展生存率为51.0%、20.0%。1年、2年总生存率为36.0%、7.0%。单发脑 转移者DCR高于多发脑转移者(P=0.044),而男性DCR高于女性(P=0.009)。ORR和DCR在 不吸烟者、卡氏评分I>70分者、递归分隔分析(RPA)分级好者均高于吸烟者、卡氏评分<70分者、 RPA分级差者(P=0.043、P=0.001、P<0.001;P=0.009、P<0.001、P<0.001)。单因素分析 卡氏评分I>70分患者的无进展生存率和总生存率均高于卡氏评分<70分者(P<0.001和P< 0.001)。RPA分级好者的无进展生存率和总生存率更高(P<0.001和P<0.001)。不吸烟、腺癌 患者的总生存率高于吸烟、鳞癌患者(P=0.007,P=0.047)。多因素分析显示卡氏评分状况是无 进展生存期、总生存期的独立影响因素(P<0.001和P=0.005)。病理类型是无进展生存期的独 立影响因素(P=0.001)。结论厄洛替尼对非小细胞肺癌脑转移患者有较好的疗效和安全性,其 中男性、单发脑转移者DCR更高,而不吸烟者、卡氏评分I>70分者、RPA分级好者ORR和DCR均较 高。卡氏评分状况是总生存期和无进展生存期的独立影响因素。腺癌患者较鳞癌患者能够得到更 长的无进展生存期。
